In feeler. mechanism of the penetrating and impingingltype it is new the erdinz ry practice to provide a penetrating fzteelermemg her which Will penetreteer e iter the, filling on each ec'letectiii g "heat and permit the impi ngingffeeler membertotake the full front? Ward impact of the filling to move the feeler slide oh hieh the feeler members are usually whereby feeler mechanisms 6f the eelip'er ing type new employed, may bereztelily C011? vertecl into F the penetrating end impinging typeh i Y Another important feeture the in eiv tionrc'ensists in providing a 'pe etrg ting andimpinging type .of, feeler wherein the pane;

trziting member ehall be fixed to the feeler slicle and the impinging member .shellbe I rslicl ably meuiiteelen the feelerslide' to the firstv impact of the filling and then be moved frontardly t9 effect movement of the eetuator from a, n rmny Operative to 2m in.- eperativ-e position on detecting heats when a Working supply of filling is prese tin the shuttle. In accordance withthe presei'it inyeiitiq the first impact 9f the filling upon the impinging member causes the latter t0 move the ectii'zitor into itsinoperatiye pqsition when a working. supply pf filling 1S present in the 'shuttle,fancl after. such inoperative positioning of the actuator,- the preee t invention previcles that the. h ll impact of the oncoming filling shall be sustained by a member fixed to' the :feeler sli cle.

Other features of the invention reside in details of construction whereby the general objeets of the present inventior are eflteetively carried into operation.

the: present instance the feel'er :IS' ail-'- weiid y y heusu p i e ivetelly sup wt 1 .991 the pqe l l ,Q15' l; 17 1's the fiwtli itm jls, the frehtwarrlly twhiehie ormal y peeithe V Jeing that upon such engagement filling replenishment will be initiated.

Extending downwardly'from the actuator 18 is a heel 20 adapted to be struck by a bunterrcarried by the impinging feeler member, as will presently appear, and thereby move the actuator from its lowered or operative position to its upper or inoperative position when a working supply of filling 18 present in the shuttle on a detecting beat.

The lav carries the usual shuttle box 21 in which the shuttle22 is received and the front'walls of the shuttle and shuttle box are provided with openings 2& which register when theshuttle is in proper position in the shuttle box, the construction being such that on detecting beats, the feeler (presently to be described) will enter the shuttle and detect the condition of the filling.

The feeler'slide 15 has at its rear end portion a penetrating feeler member 25 .which is located at one side of the feeler slide and is adapted to, enter or penetrate the filling when, on a detecting beat, a working supply is present in the shuttle.

Mounted upon the feeler slide 15 is an im- [pinging feeler member 26, best shown in justably connected to the impinging feeler member 26 is the hunter 30 having an end portion 31 adapted to engage the heel 20 of the actuator. The bunter 30 15 formed as a plate and is also provided with an elon-' gated slot 32 through which passes the bolt 33 which is screw threaded at its lower end to receive a nut 34, whereby. the impinging iiember26 and its hunter 30 may be adjustably associated to effect movement of the actuator into its inoperative position when the impinging member 26 is moved frontwardly by a working supply of filling on a detecting beat.

In accordance 'with one feature of the presentinvention, the impinging member 26 is utilized to effect movement of the actuator from its normally operative to an inoperative position when the impinging mem.

her is pushed frontwardly by a working supply of filling on a detecting beat, and

upon the completion of such inoperativepm sition of the actuator, the frontward push of the filling is sustained by the feeler slide to efiect frontward movement thereof, and thus relieve the impinging member from its stress.

In the present instance of the invention, the impinging feeler member 26 is confined to its guideways on the feeler slide by means of a cover plate 35 which may be secured by pins or bolts 36 to the rear end portion of the feeler slide. Therear end portion 37 of the cover plate 35 extends rearwardly beyond the rear end of the feeler slide 15, with the result that when a working supply of filling is present in the shuttle on a detecting beat and the impinging member 26 is moved 'frontwardly to inoperatively p0sition the actuator, the frontward stress of the oncoming filling is taken by the rear end portion 37 of the cover plate, the result being that the impinging member 26 by its sliding movement on the feeler slide serves to inoperatively position the actuator by the frontward impact of the filling and upon the completion of such inoperative.position of the actuator, the feeler slide itself through the rear edge portion 37 of the cover plate sustains the frontward pressure ofthe filling which serves to move the feelerslide and the actuator frontwardly.

Inasmuch as the function of the impinging member 26 is confined to inoperatively positioning the actuator, it is important that ghe position of the hunter 30 on the impinging member shall be accurately adjusted to' effect such movement of the actuator and thereafter permit the rear end portion 37 of the cover plate to take the full impact 4 of the surface within the. shuttle to effect frontward movement of the feeler as a whole. 7

The rearward position of the impinging member 26 should be such that its filling engaging face 27 may extend sufiiciently far rearward of the rear end of the cover plate 37 to permit the rear end of the cover plate 37 to engage the filling when the impinging member has effected its purpose which, as

above stated, is to inoperatively position the cooperating stop formed at the front edge portion 39 of the cover plate 35.

From the construction described it will be apparent at once that the position of the hunter 30 may be adjusted byloosening the bolt 33, without at the same timev disturbing the relation ofthe cooperating stops 38 and 39. Similarly, the position of the stops which determine the rearward position or" the impinging member may likewise be ad-' justed without at the same time'disturbing the relation between the impinging member 26 and the bunterj 30.

lVhen a working supply of filling is pres-' ent in the shuttle on a detecting beat, as indicated in Figs. 12 and 3, the penetrating member, and move it frontwardly to an ex tent preferably sufiicient only to move the actuator from its operative to its inoperative position, and thereupon the filling engages the rear end portion 37 01": the cover plate 85 and pushes the feeler slide frontwardly,

. thereby taking the stress of the. frontward pressure. When, however, the filling is substantially exhausted on a detecting beat, asv indicated in Fig. 4, the penetrating feeler member 25 will meet the more dense surfacev of the filling carrier or bobbin and the impingingfeeler member 26 willnot be moved frontwardly relative to the feeler'slide, with the result that the actuator will remain in operative position and on frontward'movev ment of the feeler slide will effect replenish- I ment of filling.
